FINGER RING.

Application filed. May 10, 1921.

To all whom it may concern Be it known that I, DOMENIOO P. F ON- TANA, asubject of the King of Italy, and a Finger Ring, of whichthe followingis a full, clear, and exact description.

This-invention relates to jewelry and refers particularly toimprovements in the construction of finger rings.

In the common form of finger rings which are of solid construction, itis essential to make the internal diameter of the ring body ofsufficient size to readily slipover the knuckle, and this constructionvery often results in a loose fit of the ring on the lower joint ofthefinger. I

. Other disadvantages resulting from this construction reside in thedifiiculty of removing the ring, in some cases an impossibility withoutcutting the same from the fin e he present invention contemplates afinger ring construction in which the ring body is constructed ofhingedly connected sections which permit of the opening of the ringduring its application or removal to eliminate the above mentionedobjections and disadvantages.

A further object in view resides in the provision of an effective meansfor connecting the sections to each other, which means is not readilydetected and which is positive and eflicient in its purpose.

A. still further object in view resides in the provision of a ringincluding a hingedly connected section in which the means of connectionprovides for circumferential adjustment whereby the diameter may beincreased or decreased.

With the above recited and other objects in view, the invention residesin the novel construction, combination and arrangement of parts setforth in the following'specification, pointed out in the appended claimsand illustrated in the accompanying drawing, in which- Figure 1 is aside elevation of a ring constructed in accordance with the inventionand illustrating the same in closed position.

Fig. 2 is a plan view thereof.

Referring to the drawings by characters of reference, 10 and 11designate respect vely a pair of arcuate sections which are hingedlyconnected together as at 12. The section 10 as illustrated is providedwith the usual form of setting prongs 13 to receive and hold the stonelet in place. The free ends of the sections are provided withcomplementary beveled faces 15 and 16. The section 10 is slittedcircumferentially and transversely from its free end inwardly to providean integral spring tongue 17, the outer free end 18 of which projectsbeyond the end of the section an appreciable distance to underlie thereduced extremity 19 of the section 11, the inner face of which is rabbeted as at 20 to accommodate the extremity 18 of the spring tongue 17.The meeting ends of the sections 10 and 11 are respectively providedwith a recess 21 and a lug 22 which are interengageable when thecomplementary beveled faces 15 and 16 are brought in contact. Theextremity 18 of the spring tongue is provided with an upstanding pin 23which is designed to snap in the opening 24 in the extremity 19 of thesection 11 for positively locking and retaining the sections in closedposition. The opposite side edges of the free extremity 18 of the springtongue are flared outwardly to provide laterally projecting manipulatinglips 25 which afford means for flexing the spring tongue 17 to effectthe disengagement of the pin 2-3 from the opening 24. By this arrangement and construction it is obvious that the sections may be opened toremove or apply the ring to the finger and closed when positioned on thefinger to cause the ring body to snugly fit the finger and preclude itsaccidental removal and loss.

Referring to the modification illustrated in Figs. 5 and 6, the ringsections 10* and 11 are pivotally connected as at 12* adjacent thesetting or face of the ring, in which instance the means for connectingthe free extremities of the section is disposed at the plan view thereofwith parts rear of the ring body in order to conceal said connection.The form and construction of the connecting means is identical with thatillustrated in the preferred form as well as the method and manner ofreleasing and attaching the same.

In F 7 and 8 of the drawings the ring sections 10 and 11 are pivotallyor hingedly connected as at 12" and the extremity 13 is constructed inthe form of a horseshoe, while the extremity lfir simulates the head ofa horseshoe nail. In this instance the extremity 13 is slitted toprovide a spring tongue 17" which underlies said extremity. The innerperiphery of the extremity 14" is provided with a plurality of teeth 18"which react with the single toot-h 19 projecting outwardly from the freeextremity of the spring tongue. This arrangement permits ofcircumferential adjustment of the extremities 13 and 14 to increase ordecrease the diameter of the ring. The free extremity of the springtongue is provided with laterally projecting ears 2'0 which afford meansfor flexing the tongue 17" to disengage the tooth 19 from the teeth 18for obtaining adjustments in the diameter of the ring or for opening thesections relative to each other. 1

lVhile there have been illustrated and described several preferred formsof the invention, it is to be understood that variations andmodifications which properly fall within the scope of the appendedclaims may be resorted to when found expedient.

I claim:

1. In a finger ring, a pair of arcuate sections, a hinge connectionbetween one end of each section, and means for detachably connecting thefree ends of said sections to hold the same in ring form about thefinger, comprising a circumferentially slitted porconnecting the freeends of said sections to-' gether for holding said sections in ring formabout the finger, comprising a circumferentially cutawa 1 portion at thefree extremity of one section haying an aperture therethrough, and acircumferentially slitted portion at the free extremity ofthe oppositesection having the free extremity thereof ex-- tending beyond the freeextremity of said section, and a radially disposed pin projectingtherefrom for engagement within the aperture.

3. In a finger ring including a pair of arcua-te sections having ahinged connection at one extremity, means for detachably connecting thefree ends of said sections together for holding said sections in ringform about the finger, comprising a circumferentially cutaway port-ionat the free extremity of one section having an aperture therethrough,and a circumferentially slitted portion at the free extremity thereofextending beyond the free extremity of said section, and a radiallydisposed pin projecting therefrom for engagement within the aperture,the meeting ends of said sections having complementary beveled. facesprovided respectively with-a tong and recess adapted to coact to preventlateral relative movement thereof when connection is established.
